Safety Notices
Danger notices
Attention: Inspections, installations, and service procedures are for
trained service personnel only. While the typical operator does not have
access to the product to perform inspections, installations, or service, the
following comprehensive danger notice provides instructions on how to
avoid shock hazards when working with such equipment.
danger notice calls attention to a situation that is potentially lethal or extremely
hazardous to people. A lightning bolt symbol accompanies a danger notice to
represent a dangerous electrical condition. A sample danger notice follows:
DANGER
An
electrical outlet that is not correctly wired could place
hazardous voltage on metal parts of the system or the devices
that attach to the system. It is the responsibility of the customer
ensure that the outlet is correctly wired and grounded to
prevent an electrical shock. (D004)

for installation, inspection, and service are located in the specific
installation and service guides. The procedures contained in those
publications are for trained service personnel only.
Laser safety
This equipment contains Class 1 laser products, and complies with FDA radiation
Performance Standards, 21 CFR Subchapter J and the international laser safety
standard IEC 825-2.
CAUTION:
This product contains a Class 1M laser. Do not view directly with
optical instruments. (C028)
Attention: In the United States, use only SFP or GBIC optical transceivers that
comply with the FDA radiation performance standards, 21 CFR Subchapter J.
Internationally, use only SFP or GBIC optical transceivers that comply with IEC
standard 825–1. Optical products that do not comply with these standards may
product light that is hazardous to the eyes.

Fire suppression systems
fire suppression system is the responsibility of the customer. The customer’s own
insurance underwriter, local fire marshal, or a local building inspector, or both,
should be consulted in selecting a fire suppression system that provides the correct
level of coverage and protection. IBM designs and manufactures equipment to
internal and external standards that require certain environments for reliable
operation. Because IBM does not test any equipment for compatibility with fire
suppression systems, IBM does not make compatibility claims of any kind nor does
IBM provide recommendations on fire suppression systems.
Product recycling
This unit contains recyclable materials. These materials should be recycled where
processing sites are available and according to local regulations. In some areas,
IBM provides a product take-back program that ensures proper handling of the
product. Contact your IBM representative for more information.
Product disposal
This unit might contain batteries. Remove and discard these batteries, or recycle
them, according to local regulations.

Chapter 1. Introduction
This chapter provides an overview of the IBM TotalStorage SAN Switch 2109 Model
M12 and the Model M14. For the remainder of this document, these switches will
referred to as the Model M12 and Model M14, or simply the M12 and M14.
These two switches will also be referred to as switches, when appropriate.
Information that is common for both the M12 and M14 switches will be presented
together, and information that applies to only one of the switches will be identified
specifically.
Product overview
The 2109 Model M12 and M14 switches are advanced fibre-channel switches that
are used to intelligently interconnect storage devices, hosts, and servers in a
storage area network (SAN). They are revolutionary fibre-channel switch products,
providing up to 128–ports that deliver unprecedented performance, scalability,
flexibility, functionality, reliability, and availability. See Figure 1 on page 3 and
Figure 2 on page 4.
The M12 and M14 both deliver a very high-density port, rack-ready solution to
drive cost-effective SAN.
The dual switch capability allows either one or two 64–port switches per chassis.
The switches can be interconnected to create a high port count solution, or they
can be used in a dual fabric, high availability topology.
The switches support 1 Gbps and 2 Gbps auto-sensing fibre-channel ports.
Trunking technology groups up to four ports together to create high performance
Gbps ISL trunks between switches.
Universal ports self-configure as E_ports, F_ports, or FL_ports.
Small form-factor pluggable (SFP) optical transceivers support any combination
short wavelength (SWL) and long wavelength (LWL) optical media on a single
switch module.
The switches offer a high availability platform for mission-critical SAN-designed
applications.
Dual redundant CPs provide high availability and enable nondisruptive software
upgrades.
Both switches offer forward and backward compatibility with all IBM SAN
switches.
The Fabric operating system (OS) delivers distributed intelligence throughout the
network and enables a wide range of value-added applications including
Extended Fabrics, Fabric Access, Fabric Watch, Remote Switch, Web Tools, and
Advanced Zoning.
High availability redundant design, extensive diagnostics, and system monitoring
capabilities integrated with Fabric OS management tools deliver unprecedented
reliability, availability, and serviceability.
The switches are nonblocking core fabric switches. They never prevent a server
from being able to connect to storage, even under congestion. The backplane
bandwidth between ports on the switches is sufficient to allow traffic to flow at full
bandwidth.

Throughput
Link distance
The M12 and M14 provide continuous and sustained bandwidth to all ports in a
single or dual 32-port or 64-port switch scenario at their rated line speed.
Throughput is 2.125 Gbps inbound and outbound per port. All ports can be
simultaneously loaded for up to 100% utilization at full bandwidth. The M14
backplane provides support for a 128-port switch, 10 bps fibre channel, IP
connectivity, application processing and Infiniband.
Each port on the switch is auto-sensing and supports 1 Gbps or 2 Gbps speeds.
You can manually set the ports to support either 1 Gbps or 2 Gbps links. The ports
perform speed-matching, which allows 1 Gbps and 2 Gbps links to mix on any route
within the fabric. When there is 1 Gbps in and 2 Gbps out, the ASIC delays
transmitting the outbound frame until half the frame is received at 1 Gbps. With 2
Gbps in and 1 Gbps out, the ASIC delays releasing the buffer to ensure that the 1
Gbps transmit port has adequate time to empty it.
The M12 and M14 operate at up to 10 km (6.21 mi) at both 1 Gbps and 2 Gbps
speed settings and supports LWL SFPs and single-mode fiber.
Using the Extended Fabrics optional software feature, the switch operates at
distances greater than 10 km (6.21 mi) using various methods. The switch
leverages the current dense wavelength division multiplexing (DWDM) certification
and is certified to interoperate with equipment from Optical Networks, Cisco
Systems, Inc., Nortel Networks, and other leading vendors.
The switch operates at near full link speed at distances up to 100 km (62.13 mi) for
Gbps or 50 km (31.06 mi) for 2 Gbps speeds using the Extended Fabrics feature.
For information about Extended Fabrics, see Brocade Design, Deployment, and
Management Guide.
SFP fiber optic transceivers
Each 16–port card (blade assembly) supports up to 16 SFP fiber optic transceivers
that convert electrical signals to optical signals (and optical signals to electrical
signals) and are capable of transmitting at both 1 Gbps and 2 Gbps speeds.
Each SFP fiber optic transceiver supports 850 nm SWL, on multimode fiber optic
cable, or 1310 nm LWL, on single mode fiber optic cable. These miniature optical
transceivers meet the high port density that is available in the M12 and M14
switches, deliver twice the port density of standard removable GBIC transceivers,
and are encased in metal or shielded plastic to ensure low emissions and high
thermal management. SFP devices are hot-swappable and connections are through
industry-standard LC connectors.

Chapter 2. System design overview
The M12 and M14 switches are designed with a number of features that ensure
that these switches are highly available, reliable, and serviceable. These products
have a number of modular design features, allowing for ease and speed of
maintenance, as well as future expansion. Some of the basic features are shown in
Figure 1 and Figure 2 on page 4, and are described in sections below.

Figure 2. Port side of the 2109 Model M14
The chassis sizes for the M12 and M14 are identical. There are differences in the
number of power supplies provided in a standard configuration, and in the CP and
16–port cards that populate the different model chassis. The blower side of both
models is identical, consisting of three blower assemblies and a WWN bezel which
displays summary status LEDs, as shown in Figure 3 on page 5.
